Be it known thatv i, Josicrii A. YottNG, at citizen ol' the United States, und a resident of the city oi' New York, borough of Brooklyn, in tho countyoi Kings iindStuteoi New York, have invented s. new und improved Non- Slipping Tire and Brake. ot` which the followine is a full, clear, snd'exuct. description.

ily invention relates to vehicles, my more particular ohiect being to produce o wheel provided with a tire constructed for the purpose of preventing slinping und provided with s brake peculiarly adapted for this forni of tire.

Reference is to he had to the accompanying drawings, forming :i part of this specification, in which similar characters of reference indicate correspondingf parts in all the figures.

Figure l is ii side elevati ion of the wheel and brake, embodying my invention, certain partis being broken uwziy l'or the sake of clearness. Fig. 2 is s fragmentary phin View of the tire, showingr means whereby the, segmental shoes muy he mounted in position. Fig. 3 is n fragmentary elovation, enlarged, showing the bottoni portion of the tiro, the segmental shoes heinf shown partly in section on the iino 3 3 of "ie: Fig. 4 is :in en lnrged section upon the .tuesk 4 of Fig. 1,look ing in the direction of the arrow and showu ing the manner in which the seementul shoes are mounted. Fig. 5 is zin eniiirged section upon the line 5 5 of Fig. 1 looking in the direction of the arrow and showing the brake to father with its mountings, and Fig. o is nn en ar ed'fagnentary section upon the line 6 6 o? Fig. i looking in the direction oi the arrow and showing the construction of one of the segmental shoes.

Thr hub of the wheel is shown zit 6. the s okes ot 7, the folly at 8, and n tire nt 9. his tire is provided with o colnporzttivoly narrow portion or neck 9, upon each side oi which ore fitted blocks 10, secured thereto h means of oolts l1, passing entirely throw?. "the i" ond'thiough the neck QF, The blocks l() are each provided with dovrei corners i2, whish raisin them in proper relation to the tiro. Threaded upon the tire 9 are o number of segmental shoes 13, each provided .with s convex surface. 1 3 having on s erture 13a, as indicated in igs. 3, 4, on 5. This aperture is for the purpose of rsifontin@ the accumulation of dirt; within t o severo shoes. therein is free to roll down through the oper- Any dirt which tends to accumulato l tures and make its escape. The apertures also serve to divide the hearing-surface upon opposite sides of n common line, and this renders the. shoes less linhle to the effects of friction. Each se mental shoe 13 is further provided with e. s ot 14 s little wider than the, thickness of the felly 8, as indicated in Fig. 4, and is also provided with it recess l5, into which the slotJ 14 merges. This recess i5 is of such size as to tit loosely upon the tire. Each segmental shoe 13 is provided also with atreadsurace 16 end with cushions 17, which serve its huiiers to prevent undue noise und shock, which might otherwise ensue from adje-cent segmental shoes knocking together. The brake-shoe is shown at. 18 and is provided with grippingsurfsces i9 20 :md with journals 2i 22. 'Nie journal 22 works in a beiirin r 23, carried h v a bearing-plate 24, the hitter eing held o3 holt-s 25 upon a portion 2o of the vehicle. A bracket 27 encargos the journal 2l and assists in supportingtlhc hrnlteshoe 12%. liigidly connected with the hrnkcshoe IS is un arm '225, und pivoter! to this ztrzn is u pitnmn 29, connected with a lu'niic-lever 3U, ront 'olliiolc by hand in the usunl inunncr. The tire is of cqunl width throughout its eittire circi 'micrcncc notwithstuuding the presence oi lhe blocks lib-that is to sity, these blocks being let simplv into the tire, es indiexited in Fig 2, the width of the tire is thus rendere-d uniform. This width is considerublv grezitcrfthun the width of the feliy 8, as indicated itt-Fig. 4, so that the segmental shoes 13 wli'eh their recesses 15 nrtially encircle the tire are not onlv held oosely upon the tire, hut aire euch maintained in n predetermined .iroximsto rehttion thereto. `Tlio number o' the segmental shoes is such as to slidel on about seven-rights oi the tire, the remaining portion appearing exposed, as indicated in Fig. 1.

The operation of my devieeis as follows: Wi en the wheel rolls forward or backward. the ire 9 presses tightly upon the convex surn foco ib o such ol' the shoes as hapocn'to be in engagement with the ground. he curvtiturs of 'the portion 13b being convex and the outer periohery ot' the tire 9 boing" :rt-iso convex, it follows that the motion of the tire relatively to the shoe is a sort of rolling motion. The wheel :is a whole thus has a limited movement relatively to the shoe or shoes which happen to enii e the ground at a particular moment. At east one of the shoes 13 has its tread-surface inactucl con- IXO
